3DEC is a three-dimensional numerical modeling code for advanced geotechnical analysis of soil, rock, ground water, structural support, and masonry. 3DEC simulates the response of discontinuous media (such as jointed rock or masonry bricks) that is subject to either static or dynamic loading. The numerical formulation It is based on the distinct element method (DEM) for discontinuum modeling.

Dear colleagues,
I have written a code in 3DEC version 5.2 for simulating fallout at deep underground mines. The code ran correctly on this version, and I then converted it to 3DEC version 7 using the same parameters. However, while the code on version 5.2 reached equilibrium after one day, the version 7 code did not after 1 week.
I assigned high-strength joint parameters before excavation for both models. once it reaches equilibrium, I will change the joint parameters to their real values before excavation. For ‘block contact material-table default prop’, I assigned real joint parameters. I would appreciate any assistance in understanding why the version 7 code did not reach equilibrium.
